Helical Pitch Parameter Dependency of High Beta Equilibrium of Helical Plasmas

抄録

The helical pitch parameter (γ) dependency of equilibrium and the stability of the high beta plasma in the LHD type magnetic configuration is studied numerically. It is confirmed that the small γ configurations are favorable for the LHD-type fusion reactors in the point of robustness of high beta equilibrium, compatibility of easy ignition and high output power of core plasma, in addition to a sufficient space for blankets.
